What GTB does

GTB Co., Ltd. (株式会社ジーティービー) is a privately held, bootstrapped Japanese independent software company headquartered in Kobe, founded in 1990, with 11–50 employees. It specializes in image-processing technology applied to pre-press proofing, print inspection, plate verification, and CTP workflow for the Japanese printing industry, where its Hallmarker series holds the claimed No.1 share in print-inspection software with 1,000+ installed licenses.

The company's product architecture is organized into four pillars: (1) the Hallmarker family (Hallmarker, HallmarkCenter, Ken2Pa!, HallmarkerElements, Hallmarker DI, Hallmarker for CAN) — software for comparing digital data against printed materials and against other digital data, driven by a proprietary EyeMine fuzzy inspection engine; (2) the CorrectEye family of hardware inspection systems (CorrectEye SIS non-contact scanner in standard, wide, quality-management-server, and compact variants; CorrectEye with CCD Scanner) that perform offline inspection of wet prints, folded materials, flexible packaging including 12-micron PET film, foils, and transparent substrates using a proprietary distortion-correction engine; (3) the Bit-Through series for 1bitTIFF editing and CTP workflow (Digital Plate Checker, PlatePlanner, ProofMaker, JobEditor, etc.); and (4) cloud/web services including emba (proofing/approval), Weebum and OriOri! (graduation-album and school-photo sales with facial-recognition AI), and the W4P e-commerce/auto-ganging platform.

Revenue is generated through a mix of perpetual software licenses with annual version-up subscription programs, hardware sales of CorrectEye systems, optional add-ons (e.g., MTHQ ¥330,000, RIP option ¥550,000, DI Option, hardware-key replacements ¥33,000 each), and the newer HallmarkerElements subscription tier. Go-to-market is sales-led and Japan-domestic only, executed through direct enterprise sales supported by online demonstrations, plus channel partners SCREEN GP Japan (primary) and Media Technology Japan (secondary), with industry trade shows and print-industry publications as supporting marketing channels. End customers span commercial offset printers, educational-textbook printers, pharmaceutical/medical packaging converters, and gravure/flexible packaging operations, with named enterprise accounts including Komatsu Printing, DI Palette, Uematsu, Dai-San Offset, Dainippon Packaging, Niyodo Printing, Iwanaga Printing, and Yotsuhashi.
